When I am recording music I like to concentrate hard and use only caffeine and nicotine.
As part of live performance with Smell & Quim at maybe 10 or 12 shows since the mid-90s I can honestly say I have never been more drunk in my life than these occasions. We've taken to the stage barely able to stand, launched empty bottles at the crowd, stripped, sexually attacked crowd members in drunken ineffectual ways, fallen over, trashed our equipment, lit fires, stopped festivals, been a nightmare for venue after venue after promoter. And then moaned about not getting more bookings. It's Milovan's baby, I'm just there to help out, boy oh boy it's been fun.
Performing a couple of shows with my main (not noise) band on the experimental Shulgin chemical 2CE was...interesting. Have done shows on LSD, speed, mephedrone before. Usually just a few drinks though, unless it's S&Q when it's ALL the drinks.
EDIT duh I didn't read the topic properly. For listening to noise rather than making it, caffeine is best.
